The operator authorized the move from `3fcbb9f` (frozen `knowledge-catalog/okf/`)
to `ad30107` in `GoogleCloudPlatform/open-knowledge-format`. Cost to our fixtures
was measured at zero bytes before the decision and is unchanged: `okf_spec_commit`
is a key `STRICT_V1` names, its value is the caller's under D5, and no shipped
fixture carries one.
The old hash stays in the alignment plan rather than being rewritten. Every fact
under that heading was *read* at `3fcbb9f`; replacing the hash would give those
facts a provenance they do not have. What moves is the tree we measure against.
V-A8 re-run at the new pin: 9/9 of our golden documents parse under upstream's
reader, 0 failures, 27/27 semantic-reader calls (`trust_tier`,
`normalize_verified`, `is_stale`) return without raising. The zeroes are
measurements — the harness was put to a known-positive in both directions first:
`type: [unclosed` raises `OKFDocumentError` while a well-formed control parses,
and `is_stale` returns True for a past `stale_after` and False for a future one.
Types recovered: `ingested_at` -> str (was datetime), `generated` -> dict,
`sources` -> list, `okf_version` -> float (A-E6, still upstream's).
The `38c713f` divergence is carried forward as a written known divergence rather
than left to evaporate with the pin, and it is now recorded at pin-level
precision. `38c713f` is not an ancestor of `3fcbb9f` (`merge-base
--is-ancestor` exits 1) — it landed three weeks forward of the pin we left, so
both the old and the new pin carry the bare-scalar `tags:` form and the move
loses nothing. The accurate statement is that canonical ships a form its own
frozen predecessor has already repaired.
The open question is closed rather than deferred, because it was cheap: across
129 tracked text files present in both trees, 9 carry frozen-only lines - 8 are
`38c713f` and the 9th is the freeze notice in `README.md`. Zero files are
frozen-only. The divergence is fully enumerated.
Runbook Step 3a gains the harness trap that cost this round a re-run: the
semantic readers take the frontmatter mapping, not the document, and passing the
document raises an AttributeError that reads like an upstream incompatibility.
